To allwhom ii'may concern:

.Be a known that Lemmasn; OHnisrorrnns, a citizen of the United States, re-. siding at New York, in the county and State of New York, have made a certain new and useful Invention in Methods for Accumulating and Storing Energy.

The object of the invention is to provide va device of the character describedwhichcan be attached to any operating mechanism for accumulating and storing power under normal operation, for use when excessive" The invention consists substantially in the discovery of utilizing the wasted energy in' a rotating body, and, in the particular illuse tration, consists substantially-in the construction, combination, location and relav or load is imposed upon the source of power. For instance, a fly wheel operated by the tive arrangementof parts, all as will be more fully hereinafter set forth, as shown bythe accompanying drawing and finally pointed out in the appended claims;

Referring to the drawing: Figure 1 is a view in elevation of a structure embodying my invention.

Fig. 2 is a view in side elevation of the same.

Fig. 3 is a sectional view taken onthe line 33, Fig. 1, andlooking in the direction of the arrows.

The same part is designated by the same reference numeral wherever it occurs throughout the several view-s.-

I have discovered that a normally rotating body driven from any source under normal conditions, may be utilized to store up power in itself for use when an extra strain gas engine under normal conditions may in itself store up or accumulate power when running idly, for useful work, for example, when an additional strain or load is imposed on the engine. In accordance with my invention the momentum and weight of the fly wheel is utilized for this purpose, and while the subjectmatter of my invention is a departure to a great extent from the general application of fly wheele, it is believed that with the description thereof hereinafter set forth, it will be apparent that with small enpenm my invention may he applied readily to any eonnruetion where Specification of Letters Patent.

adapted to be operated fro eaaaa a neea, 'ilhl't.

a is. desired with small eflort a) acizomplish" results herebefore accomplished only by the use of powerful machines or great power.

Referring to the drawing, ll shfow atl a frame which is pivotally carried by jou'rnals 2 and-3 which mayform part of any suitable stationary frame work by means of sleeves 4* and 5 respectively, whereby the frame 1 may rotate'freely about said shafts tand 5. The shafts 4 and 5 shown infthe, I 1llustrat1on pass freely through the sleeves 4 and 5tand are inthe same plane and are off center relative 'to the central horizontal ax s of the frame 1. Mounted on the shaft 5 is .a sprocket or other sui able gear 14 any suitable source of power in any suitable manner.

For the purposes of description, l have shown one means which comprises a chain 15 for this purpose, but it is fiinderstood ,that' my invention is not to be; limited to this specific form as any other means of transmission of power may be employed. Also mounted on the shaft 5 is a gear wheel 13, which meshes with a gear wheel 12 mounted and secured to the shaft 10 which extends across the horizontal central axis of the frame 1. Mounted on the shaft 10, to rotate therewithisa comparatively large fly .Wheel 11 with greater peripheral weight than central weight, to secure peripheral momentum upon the rotation thereof. The

shaft 10, as shown, is carried by the frame 1. Also mounted on the shaft 10 to rotate therewith, is, a gear wheel 9, which gear wheel mesheswith a gear wheel 8, mounted on and secured to the shaft 4. Also mounted on and secured to the shaft i is a wheel 6, which wheel 6 is connected to the part to .be driven which may be any part,- and. the

connection thereof, although shown as a chain 7 may be any suitable connection.

I The operation ,of the device is apparent. The device is connected between the source of power and the part to be driven; Power is transmitted, in the illustration shown,

through the chain 15 to wheel 14, thereby rotating the shaft 5 and gear wheel 13, and the rotation of the gear wheel 13 in opera tion rotatesgear 12, fly wheel 11, gears 9, and 8, shaft 4L and consequently gear 6, thus imparting ower through the chain 7, to the part to driven.

Assume that a strain or load is imposedupon the part to be driven; it is apparent that the frame 1 will rotate about the shafts lliih 4 and 5, as the shaft 4 is for the moment being held stationary by the load, the wheels 8 and 6 likewise being held stationary,' the gear 9 will travel around the gear 8, thereby rotating the. frame 1 about the shafts 4C and 5. Frame 1 will rotate about the shafts l and 5 until the weight of the wheel 11, added to the momentum thereof plus the source of power, which has remained constant throughout, is suflicient to cause the rotation of the wheel 8, the shaft 4 and wheel 6, thereby without any additional power at the source adding suflicient power, stored up or accumulated in the fly wheel, to overcome the added load on the part to be driven. For a concrete illustration, assume the wheel 14; to be connected to the sprocket wheel of a bicycle and assume the wheel 6 is connectedto the driving wheels of a vehicle. The normal operation of turning the bicycle sprocket being imparted to the wheel ,14 and thus through the connections tothe cient to operate the Vehicle.

power, and a part to be driven, means interwheel 6 causes the vehicle to be impelled forwardly. When, however, a load. s imposed upon the vehicle, which usually would require an additional source ofpower at the bicycle, the sameamount of power at the bicycle causes the gear 9 to ride on the gear 8 until the power'derived from the momentum and weight of the fly wheel 11 is sufli- It is obvious that the more load that is applied upon the vehicle the farther thev gear wheel 9 will climb on the gear wheel 8, but at no time is added power necessary at the source. I

It is apparent that this principle may be applied in any instance where a source ofv power is to be transmitted to a variable load, for examle, on automobiles, or the like.

While I have set forth one specific application of my invention and have shown and described a specific structure ambodying the principles thereof, I wish it to be understood that my invention in its broad scope is not to be limited thereto, as many applications and many structures embodying the principles of my invention will readily ocposed between the source of power and the part to be driven displaceable relative there to, and actuated by the source of power, for
